Moving toward using self and parent to resolve things

...in order to ease writing motives like NamespaceMotive
Resolving mostly via parent, some stuff is still on context, and the rules for resolving things are only halfway-there
Sketched in resolution for constants within a namespace
Made NeedsMotive resolve the mote
Cleanup and note-taking
Sketching out resolution system
Started implementing motive resolution
WIP resolving things
Started adding MotiveInstance to Motive
Removed references to Motivator in most places, starting real motive resolution
Resolving motives recursively now!
Moving toward more recursive identifiers and resolvers rather than motivator references
And now everything is pretty happy
Returning to Cucumber to focus on high-level functionality, filling in methods as needed and starting broader unit tests
